Hi I just got a new Guinea pig as a friend for my older one, but I have to quarantine them apart. The new one that I got comes out when I leave, but once I enter the room she either sits there not moving, or runs to the giant temporary box hidey we made her. I have tried putting food in front of her face, and she just ignores it and runs past. Are old one was already eating from are hand the 2nd day we got her, so I'm not sure how to get this one to come out. She is about 3 months old while the other one is about 2 years.
